VF: Missing HVAR in Glyphs, Axis Mapping and DC CP Problems in fontmake

aminabedi68 · February 4, 2026, 1:09pm

i did publish a new release for Estedad, I ran into a couple of issues and would appreciate any insight:

1- Glyphs app do not generate hvar table, which causes a fail report in FontBakery.

2- fontmake output dose generate hvar table, but couldn’t handle the Axis Mapping and Decompose Components CP(i wonder if is it related to glyphsLib or not)

(I tried merging the hvar table from the fontmake built version into the Glyphs generated version of the font via scripting using TTX. While this technically works, it completely breaks all sidebearings)

What fontbakery profile did you use?
hvar is technically not required, the font works fine without it.

I use check-googlefonts profile.

Here is the fail link:

P0 Urgent

## Observed behaviour Not having a HVAR table can lead to costly text-layout …operations on some platforms, which we want to avoid. ## Expected behaviour Add a check for presence of HVAR table with valid values in all VFs. ## Resources and exact process needed to replicate https://docs.microsoft.com/en-us/typography/opentype/spec/otvaroverview#variation-data-tables-and-miscellaneous-requirements

and what about not working Axis Mapping and Decompose components CP via fontmake? Should i report on fontmake’s github page?

The google profile should only be used for google fonts. They are overly strict.
The problem with the axis mapping is a glyphsLib problem.
